As part of a programme on the characterization of the growth pattern of the apple-tree, uniform 1-year-old plants carrying two new shoots were grown for a season under 100, 78, 41, or 24 per cent, natural light. Weights of leaf, new stem, old stem, and root were determined by sampl...
Effects on Apple Tree Growth and Light Interception in Three Training Systems over Ten Years The effect of increasing planting density at constant rectangularity on the fruit yield, fruit size, and fruit color of apple [Malus xsylvestris (L) var. d... CR Hampson,HA Quamme,F Kappel,... -...
All rates of K increased tree growth and yield in years 1 to 3. As cropping increased, rate effects tended to increase up to 75 kg K/ha per year. In the first 4 years, fertigation with EDTA chelates of Zn or Cu have been more effective than sulfates in increasing leaf Zn or Cu, ...
Apple Tree is a business growth forecast app that allows you to visualize your small business's growth fully through a series of simulations. Apple Tree is equipped with a useful collection of Simulation Models like the Apple Tree calculator (growth, App
tree livability was reduced;tree growth was weakened;ground subsidence depth was deepened in plant year;branch water content was reduced in the winter and spring;branch shriveling index was increased;and tree survival rate was decreased.Soil preparation by digging hole before rainy season is suggested...

摘要: This article describes the growth of an apple grows on an apple tree. An apple blossom blooms until the petals fall off. Then a tiny apple grows. First, the apple is green and it gets bigger and bigger. When the apple is big and red, it is ready to be eaten. 年份: 2005 收...
The results revealed much larger nutrient inputs than outputs, with N, P, and K surpluses 1.8–4.0-fold higher than required for apple tree growth. The huge N surplus caused nitrate accumulation and acidification in deep soil under apple orchards (up to 6 m). Soil nitrate storage in 25-...
These research results mainly focus on the mechanism of fruit quality formation, metabolite markers of special quality or physiological period, the mechanism of fruit tree's response to biotic/abiotic stress and environment, and the genetics mechanism of fruit trait. According to different experimental...
